Hst in Ontario Calculator

Reviewed by Calculator Editorial Team

Ontario's Harmonized Sales Tax (HST) is a consumption tax that combines the provincial sales tax and the federal Goods and Services Tax (GST). This calculator helps you determine the HST amount on purchases in Ontario, understand how it applies to different products, and learn about exemptions.

What is HST in Ontario?

Harmonized Sales Tax (HST) is a single sales tax rate that combines Ontario's provincial sales tax and the federal Goods and Services Tax (GST). It was introduced in Ontario on July 1, 2010, as part of Canada's national harmonization of sales taxes.

The HST system simplifies the tax process for businesses and consumers by replacing the previous system where both provincial and federal taxes were applied separately. Instead, a single tax rate is applied to most goods and services sold in Ontario.

Key Points About Ontario HST

  • HST is charged on most goods and services sold in Ontario
  • The tax rate is applied at the point of sale
  • Businesses collect HST from customers and remit it to the government
  • HST is not charged on certain exempt items

How HST Works in Ontario

When you make a purchase in Ontario, the seller adds the HST to the price of the goods or services. The total amount you pay includes the original price plus the HST. Here's how it works:

  1. You purchase an item in Ontario
  2. The seller calculates the HST based on the current rate
  3. The total price (original price + HST) is displayed
  4. You pay the total amount
  5. The seller collects the HST from you and remits it to the government

HST Calculation Formula

Total Price = Original Price + (Original Price × HST Rate)

HST Amount = Original Price × HST Rate

For example, if you buy a $100 item with a 13% HST rate, the HST amount would be $13, and the total price would be $113.

Current HST Rates in Ontario

The standard HST rate in Ontario is currently 13%. This rate applies to most goods and services sold in the province. However, there are some exceptions and special rates:

Category HST Rate Examples
Standard Rate 13% Most goods and services
Zero-Rated Goods 0% Prescription drugs, medical devices, and certain agricultural products
Exempt Goods Not subject to HST Basic groceries, prescription drugs, and certain services

It's important to note that the HST rate can change. Businesses must keep up with any updates to the tax rates. The government typically announces changes well in advance, so businesses have time to adjust their pricing and collection methods.

How to Calculate HST

Calculating HST is straightforward once you know the current tax rate. Here's a step-by-step guide:

  1. Determine the original price of the item or service
  2. Find the current HST rate (typically 13% for most items)
  3. Multiply the original price by the HST rate to find the tax amount
  4. Add the tax amount to the original price to get the total price

HST Calculation Example

Original Price: $150.00

HST Rate: 13%

HST Amount = $150 × 0.13 = $19.50

Total Price = $150 + $19.50 = $169.50

This calculation applies to most goods and services in Ontario. However, some items may be exempt from HST or subject to different tax rates.

HST Exemptions in Ontario

Not all goods and services are subject to HST in Ontario. There are several categories of items that are exempt from the tax:

  • Basic food and groceries
  • Prescription drugs
  • Medical devices and equipment
  • Certain agricultural products
  • Services provided by non-profit organizations

Important Notes About Exemptions

Exempt items are not subject to HST, but they may still be subject to other taxes or fees. Always check the specific tax rules for the item or service you're purchasing.

If you're unsure whether an item is exempt from HST, you can check the Ontario government's website or contact the retailer for clarification.
